Example Embodiment

[0029] The present invention will be further described in detail below with reference to the drawings and embodiments.

[0030] Take the application of this scheme in retarder waterway as an example to illustrate. The retarder is an auxiliary braking device for the vehicle, which converts kinetic energy into heat energy during braking, and finally dissipates heat into the air through the vehicle cooling system. The heat dissipation of the vehicle determines the braking power of the hydraulic retarder.

[0031] Such as figure 1 As shown, a vehicle heat dissipation system for matching a hydraulic retarder is connected to the engine 8 and the transmission 9; it includes a cooling circuit system, an electronic water pump 3, a water temperature sensor 7 and a control module 11, and a cooling circuit system Including the heat dissipation water tank 1, the original car water pump 4, the engine water inlet pipe 5 and the engine water outlet pipe 6; the water outlet of the original car wate...

Abstract

The invention discloses an automobile heat radiation system matched with a hydraulic retarder and a control method of the automobile heat radiation system. The automobile heat radiation system comprises a cooling loop system, an electronic water pump, a water temperature sensor and a control module. The cooling loop system comprises a heat radiation water tank, an original automobile water pump, an engine water inlet pipe and an engine water outlet pipe. A water outlet of the original automobile water pump is communicated with the engine water outlet pipe, the engine water outlet pipe is communicated with a water inlet of a retarder, a water outlet of the retarder is communicated with a water inlet of a thermostat, a water outlet of the thermostat is divided into two communicated with a water inlet of the heat radiation tank and a water inlet of the original automobile water pump respectively, a water outlet of the heat radiation water tank is communicated with the engine water inlet pipe, and the engine water inlet pipe is communicated with the water inlet of the original automobile water pump; the electronic water pump is arranged in parallel to the original automobile water pump, and the control module controls opening and closing of the electronic water pump. The automobile heat radiation system is simple in structure and capable of meeting requirements of heat radiation of the automobile cooling system and is oil saving.

Description

technical field [0001] The invention belongs to the technical field of automobile heat dissipation, and in particular relates to a vehicle heat dissipation system and a control method for matching a hydraulic retarder. Background technique [0002] When the actual working condition of the whole vehicle (downhill working condition of the retarder or heavy load climbing working condition) has special requirements on the cooling system, it is necessary to increase the heat dissipation of the cooling system of the whole vehicle. There are three ways to increase the heat dissipation of the vehicle: 1. Increase the area of ​​the cooling water tank; 2. Increase the diameter of the cooling fan; 3. Increase the diameter of the water pump impeller or increase the speed of the water pump. The first two methods are limited by the width of the frame of the whole vehicle, the range of increase is not large, and the effect is limited. And adopting the third way will increase the fuel cons...
